To me, it doesn't mean much. Posturing that if Russia committed cyberattacks on the U.S while she was president, she would consider political, economic and military responses is not a surprising statement.
A military response against Russia could easily involve increasing support for Syrian rebels to foil Russian interests there etc.
Anyway I'm not here to defend Hillary, don't like her at all. Just think that on balance she is lesser of two evils. I think people when voting for Trump didn't realise quite how he would turn out. There was a wave of hysteria for Trump, like there was for Obama in 2008. But in both cases it has turned out wrong.
